PV píše:The timeline shows that the crew switched the STAB TRIM switches to CUT OUT at 05:40:35, 2mins and 35s after take-off. But at 05:41:46, the Captain asked the First-Officer if the trim is functional. The First-Officer has replied that the trim was not working and asked if he could try it manually. The Captain told him to try. At 05:41:54, the First-Officer replied that it is not working. I am not sure if this means that manual trim was not available.
At 05:43:11, about 32 seconds before the end of the recording, at approximately 13,4002 ft, two momentary manual electric trim inputs are recorded in the ANU direction. The stabilizer moved in the ANU direction from 2.1 units to 2.3 units. This suggests that the STAB TRIM switches were returned to the ON position.
Na mě to dělá dojem, že proto, aby jim fungovaly manuální trimy, zkusili na "bezpečné" výšce zapnout cut out switch. Neměli ovšem plně vytrimováno, knipl měli asi na půl výchylky na sebe, čert ví, jaký byl elevator feel. Ve chvíli, kdy se aktivoval MCAS, přešel MAX prakticky okamžitě skoro do pádu, a i když přitáhli co mohli, nebyli vůbec schopni letadlo zvládnout, a během 15s narazili do terénu. Ta rychlost, se kterou sestřelil MCAS letadlo z oblohy, je děsivá.
Jen pro zajímavost zkratka MCAS se v reportu vůbec nevyskytuje.
